Nonpoint Source Success Story: Tarkiln Run
Maryland's 2015-2019 Nonpoint Source Management Plan (2016 Update)
Nonpoint Source Pollution (NPS), unlike pollution from industrial and sewage treatment discharge pipes, comes from many diffuse sources. This type of pollution is called nonpoint source pollution because it does not come from a single outlet, waste pipe, or "point" source. NPS is caused when water from rainfall or snowmelt moves over and through the ground. During this movement, the water picks up and carries away natural and human-made pollutants. Eventually, this water, with the pollutants it carries, reaches lakes, rivers, wetlands, coastal waters, and even our underground sources of drinking water.
Nonpoint Source Pollution is one of the major contributors to degradation of Maryland’s waterways and the violation of water quality standards. The kinds of pollutants associated with nonpoint sources are diverse and potentially include:
Managing Nonpoint Source Pollution
Maryland's nonpoint source pollution problems are as diverse as its landscape. In response, the State’s strategy is to pursue a wide array of nonpoint source pollution control programs that are aimed at combating these varied pollution sources. The goals, initiatives and partnerships that make up this strategy are described in Maryland's 2015 - 2019 Nonpoint Source Management Plan (PDF).
NPS Implementation Funding - Priority Watersheds for the 319(h) Grant (A-I Watershed Plans)A prerequisite for §319(h) funding of implementation projects (any project involving in-the-ground construction) is EPA acceptance of a watershed plan. See MDE’s 319(h) Grant Program web page for EPA Accepted Watershed Plans.
